Using type to return objects to Flex
Author: Gareth Arch

Yeah, I finally finding that out (after many trials), I was wondering if BlazeDS
+ CFMX7 would work using the __type__ method? I didn't know if that would
translate the structs to objects before passing it off to ActionScript.

I don't think it will be possible in cfmx7 (I might be wrong) but I
think that __type__ solution was introduced with CF8 for supporting
faster object creation for LCDS 2.5.1 data management destinations.

Just figured I would post a follow up here for anyone who is following along (or
may be in the future). I've tried way too many different things with settings
files and could not get it working. Jon Messer retried and found that it was
using a CF8 instance from his CFMX7 install, so was not actually using CFMX7 to
return the values, so thus far returning objects by just using remote object on
CFMX7 does not appear to work unless using LiveCycle or some other dataservices
intermediary. If anyone does get it working (or knows some alterations on CFMX7
to get it working), please post. Thanks.

I think there must be a setting that I'm missing. I copied the code over to new
install of Eclipse 3 and CF8 (on a clean PC) and ran the code and it returned the
correctly Typed Objects (instead of the generic objects I was seeing). I'll
probably go through some of the files and see if there's something that's
installed on the new copy vs. my local copy. There are quite a few xml files in
my jrun folder that may be affecting things. I'll have to check it out and see.
What's really frustrating is that if I knew it *didn't* work in CF7, then I would
just stop, but as I know it *does* work and is insanely faster than instantiating
objects in CF (and transferring them back to AS), that I really want to get it
working.
Do you guys think that it is one of the XML files that is causing the weirdness
or another setting? I just want to make sure I'm focusing my efforts in the
correct area.
Thanks.

Did you reboot and clean re-compile both ends ?

And one other thing to mention (that hopefully wouldn't have made a big
difference). Our environment is running through JRun server. I don't think that
would make any difference, but it's something else to note.

I don't know what to say.
That exact code (and only that code) works for me on a Mac CF8, on Linux CF8
and Windows CF7. The only difference I see is that I didn't run it over SSL
and it looks like you are, but I use this method in production with SSL.
I'm at a total loss... :-(

I swear, I'm not starting to believe it myself :)
I actually did have a Test.mxml page that was instantiating the TestClass, but I
didn't add that bit. Sorry about that.
OK.
I pasted the code you sent (exactly as sent into separate files) and I still get
the generic objects returned. My code is outputting to
C:\Inetpub\wwwroot\OptimizationDemo
Do I need to do something else to aliases if I it is setup like this? I have my
https://localhost pointing to C:\Inetpub\wwwroot\OptimizationDemo though, so my
test page would be https://localhost/Test.html My CFCs are also right in this
folder.
As long as you keep giving me hope that this really does work, I'll keep making
changes to try to get this working :)

*Ahh*, I bet that's it.
We'd normally have some component somewhere with a variable of the RemoteClass
type, so this doesn't occur - it's basically because the demo code is *too*
simple :-)
All Gareth needs to do is add
import TestClass;
private var dummy:TestClass=new TestClass();
to his SWF app. somewhere. Anywhere :-)

So you're saying that the EXACT same flex code and the EXACT same cf code
with this one change in buildStruct everything works?
//arrayAppend( ret, duplicate( obj ) );
arrayAppend( ret, CreateObject("component","TestClass") );
You shouldn't even recompile the flex app, just change that one line in your
TestGateway and then everything works?
I don't mean sound rude or to sound like I don't believe you but I find that
pretty hard to believe.
I ran the code you posted and as I would expect it is receiving a generic
object in both cases, because there is no instance of TestClass compiled
into Test.mxml. As soon as you compile TestClass into the app it works for
both cases with the code you posted...

Here's what was output (I wasn't sure *exactly* what was needed, so I copied as
much as seemed pertinent...I trimmed anything that was repeating too much) Let
me know if there's something else that I need to change or more info that you
need.

_ro.source="TestClassGateway";
_ro.destination="ColdFusion";
_ro.showBusyCursor=true;
_op=Operation(_ro.getOperation("getAll"));
_op.addEventListener(ResultEvent.RESULT, receiveAll);
}
public function getAll():void {
_ro.getAll();
}
public function receiveAll( event:ResultEvent ):void {
this.dispatchEvent( new Event( TestClass.ALL_RECEIVED ) );
}
I put a breakpoint at the dispatchEvent point so I could see what was contained
in the resultEvent.
Could you post what I'm supposed to change in my services-config.xml file to get
that working? This is what I have for <logging> in there currently
<logging>
<target class="flex.messaging.log.ConsoleTarget" level="Error">
<properties>

<includeDate>false</includeDate>

<filters>
<pattern>Endpoint.*</pattern>
<pattern>Service.*</pattern>
<pattern>Configuration</pattern>
<pattern>Message.*</pattern>
</filters>
</target>
</logging>
I also wanted to point out that I'm on CFMX7 (not 8). In the mailing list I
originally saw this on, Sean Corfield mentioned that this was available in MX7 so
I've been trying to get it to work (I just wanted to put that out there in case
that's what is messing things up).

Can you post your AS code (RemoteObject call and result handler) ?
Also, set the log level to 'debug' at the bottom of services-config.xml, and
let us know the output in the CF log file.

Thanks for taking the time to answer all of my questions...
OK,
I had been originally trying to do this in my main application, but seeing as
that wasn't working, I set up a test environment.
I've created (all in my src folder of my Test Flex project)
Test.mxml
TestClass.as
TestClass.cfc
TestClassGateway.cfc
In my gateway file I generate a struct VO. The function I use is:
<cffunction name="buildStruct" output="false" access="remote">
<cfset var i = 0>
<cfset var obj = structNew() />
<cfset var ret = arrayNew( 1 )>
<cfscript>
while (i lt 100) {
obj['__type__'] = 'TestClass';
obj['firstName'] = "";
obj['lastName'] = "";
obj['address1'] = "";
obj['address2'] = "";
obj['city'] = "";
obj['state'] = "";
obj['zip'] = "";
obj['country'] = "";
obj['email'] = "";
obj['phone'] = "";
obj['fax'] = "";
arrayAppend( ret, duplicate( obj ) );
i = i+1;
}
</cfscript>
<cfreturn ret />
</cffunction>
I use a getAll function to return this newly created VO to my calling AS object
<cffunction name="getAll" output="false" access="remote">
<cfreturn buildStruct() />
</cffunction>
My TestClass.cfc has:
<cfcomponent output="false" alias="TestClass">
<cfproperty name="firstName" type="string" default="" />
<cfproperty name="lastName" type="string" default="" />
<cfproperty name="address1" type="string" default="" />
<cfproperty name="address2" type="string" default="" />
<cfproperty name="city" type="string" default="" />
<cfproperty name="state" type="string" default="" />
<cfproperty name="zip" type="string" default="" />
<cfproperty name="country" type="string" default="" />
<cfproperty name="email" type="string" default="" />
<cfproperty name="phone" type="string" default="" />
<cfproperty name="fax" type="string" default="" />
<cfscript>
this.firstName = "";
this.lastName = "";
this.address1 = "";
this.address2 = "";
this.city = "";
this.state = "";
this.zip = "";
this.country = "";
this.email = "";
this.phone = "";
this.fax = "";
</cfscript>
</cfcomponent>
My TestClass.as has
[RemoteClass(alias="TestClass")]
public class TestClass extends EventDispatcher {
(along with getters/setters and my constructor and function call to the
TestClassGateway).
When the data is returned back to AS from CF, it is still just an array of
generic objects. If I create CF objects and return them, they come back as an
array of TestClass objects. I also noticed that in the list of properties of the
generic objects, __type__ is one of them. If it's being converted, this
shouldn't be there, should it?

Works with RemoteObject() here.

Sorry I guess I wasn't clear, you absolutely can return arrays of typed
structs and have them converted for you. That's the main point of doing
this. You can return thousands of objects in arrays, and it is ridiculously
faster then creating cfcs, you do not need LCDS to do this.
I mentioned the array because in Flex if you don't have an instance of the
AddressBook object compiled into the app, it will come in as a generic
object. But if it works when you return arrays of vos that were created with
CreateObject, then that's not the problem.
Is the AddressBook.cfc in your webroot or is it under some path?
This :
[RemoteClass(alias="AddressBook")]
will only work (with this method) if AddressBook is in your webroot, if you
use CreateObject it will work without the fully qualified path, but if you
want to use this typed struct method you have to use the full path.
So if your AddressBook is actually in com.vo.AddressBook then you have to
use
struct['__type__'] = 'com.vo.AddressBook'
and
[RemoteClass(alias="com.vo.AddressBook")]
Sorry if I am making it sound more complicated then it is, but it basically
boils down to making sure your __type__ is fully qualified and matches your
alias.

Hmmm...not too sure what you mean by this.
I had the code setup in a DAO gateway, so the <cfcomponent
alias="AddressBook"> was in an AddressBook.cfc (the code I posted was a
cffunction in AddressBookGateway.cfc). In my AS class, I have
[RemoteClass(alias="AddressBook")] to handle the class that is returned from CF
(and convert it to the correct AddressBook class). In the code, I'm trying to
return an array of AddressBook objects (thus the array that I'm returning). If I
do a createobject for CF AddressBook objects and put it in an array, it correctly
returns an array of AddressBook objects back to AS; however, if I use the
__type__ and a struct of the other variables (even with correct camelCasing), it
returns an array of generic objects. If I try a returntype of AddressBook[] from
CF, it states that it is not a valid AddressBook (which makes sense as it hasn't
been converted yet). If I can only return one item back to AS from CF using this
method, I'll probably just stick with the method I was using before (as creating
one object vs. one struct isn't going to make a big difference), but if it can
send multiple items back as VOs, then that's what I'm looking for. There's
something I'm missing between the gateway and the AS. If, as Barney states, it
is the LiveCycle intermediary, then I'm fresh out as my company won't pony up for
that, but if there's something else that I'm missing that can do the conversion
via AMF, then I'm all ears :)
Thanks.

This actually works fine without LCDS or FDS. It requires that you put the
appropriate fully qualified RemoteClass on your AS vlaue object, but if you
do that you get automatic conversion from typed CF Struct to AS.
The only thing I see that is odd about your posted code is that you are
returning an array

sorry pressed send too soon. To finish that sentence :
The only thing I see that is odd about your posted code is that you are
returning an array, so on the flex side you need to make sure that you are
compiling an instance of your VO into the application or you will get a
generic object...

No, not that I've found. But it's simple to inflate the generic
objects into typed objects in AS. Just add a static
createFromProperties(o:Object):AddressBook method that will copy
properties from the passed object into a new instance of the strongly
typed object, and then when you get your ArrayCollection in Flex, loop
over the elements and inflate each one.
var ac:ArrayCollection = event.result;
for (var i:int = 0; i < ac.length; i++) {
ac[i] = AddressBook.createFromProperties(ac[i]);
}
It's not really elegant, but it's simple, and mandatory with how slow
CF is at creating CFC instances.
cheers,

Argh! For some reason I skipped completely over that part. Other than having to
use createobject, do you know of anything that will just return the properties
rather than the whole shebang (in CFMX7)? I've returned the data as a query
before, but that then requires manipulation on the ActionScript side of things,
so if there was a way to tell it "this is an AddressBook" from CF, that would be
extremely useful (without going through LiveCycle). Thanks for the help.

How are you calling it from Flex? __type__ only works with FDS, I
believe, not with remote objects.

I am giving this a try on my current app. However, when the data is returned to
Flex, it is not of the type that I specified. All fields are camelCased
correctly (I added the properties argument to get around the uppercasing issue),
the type is set correctly, and all data is returned, but it is not of type
"AddressBook". If I do <cfreturn createObject( "component", "AddressBook"
).init( arguments.id ) /> the data is returned as "AddressBook". Any ideas?
(Code is below).
<cffunction name="getAllProperties" output="false" access="remote">
<cfargument name="queryData" type="query" required="true" />
<cfargument name="properties" type="string" required="false"
default="addressBookId,ownerId,connectionSourceId,addressTypeId,address1,address2,city,state,zip,countryId,longitude,latitude,radianLat,radianLong,lastUpdate,lastUpdateBy,lastUpdateByConnectionSourceId"
/>
<cfset var INST = structNew() />
<cfset INST.obj = structNew() />
<cfset INST.ret = arrayNew( 1 ) />
<!--- default object to addressbook --->
<cfset INST.obj['__type__'] = "AddressBook" />
<!--- loop over query --->
<cfloop query="arguments.queryData">
<!--- loop over columns and assign to temporary object --->
<cfloop list="#arguments.properties#" index="INST.property">
<cfset INST.obj[INST.property] =
arguments.queryData[INST.property][currentRow] />
</cfloop>
<cfscript>
ArrayAppend( INST.ret, duplicate( INST.obj ) );
</cfscript>
</cfloop>
<cfreturn INST.ret />
</cffunction>
